Overview:

The Blue Spot Tools 2-Piece Nut Splitter set covers nuts from 12mm to 22mm across two tools. Each splitter uses a chrome-molybdenum cutting head to crack seized or corroded nuts under controlled pressure. The outer body of both tools is made from heat-treated carbon steel. Both tools are driven by a standard hex socket or an open-ended spanner.

What's Included

• 16-22mm Nut Splitter: fits 19mm hex sockets and spanners
• 12-16mm Nut Splitter: fits 14mm hex sockets and spanners

Key Features and Benefits

• Heat-treated carbon steel body: handles the sustained torque required to split seized fasteners
• Chrome molybdenum cutting head: the hardened CrMo blade cuts through seized nuts that conventional tools cannot remove
• 12-22mm coverage: the two-tool set spans the metric nut sizes most commonly encountered in automotive maintenance
• 19mm hex drive (16-22mm splitter): works with standard 19mm sockets and spanners
• 14mm hex drive (12-16mm splitter): works with standard 14mm sockets and spanners

• Breaking free rusted brake calliper mounting bolts
• Removing stuck fasteners on agricultural or outdoor power equipment
• Splitting corroded pipe flange nuts in plumbing work
• Removing seized steering or drivetrain fasteners

How to Use

• Select the correct tool: choose the 12-16mm or 16-22mm splitter to match the nut size

• Position the tool: place the ring over the nut, aligning the cutting blade against one flat face

• Attach the drive: fit a 14mm or 19mm hex socket or open-ended spanner to the drive end

• Apply pressure: turn the drive clockwise to advance the blade into the nut

• Remove the split nut: continue turning until the nut cracks apart, then clear the pieces away

Frequently Asked Questions (FAQs)

• How does a nut splitter work?
  The ring fits over the seized nut. Tightening the drive bolt advances a hardened cutting blade into the flat face of the nut. The blade forces the nut to crack open, freeing the bolt.

• Will a nut splitter damage the bolt thread?
  Correct placement means the blade contacts the outer face of the nut, not the bolt thread. This leaves the thread below intact so a replacement nut can be fitted.

• What PPE should I wear when using a nut splitter?
  Wear safety glasses and protective gloves before use. The nut may produce metal fragments as it cracks. Keep bystanders clear of the work area.

• Do I need more than one nut splitter to cover different sizes?
  A single splitter only covers a fixed size range. A two-tool set spanning 12mm to 22mm handles the most common automotive and mechanical fastener sizes without additional tools.

• Can a nut splitter be used on stainless steel nuts?
  Stainless steel nuts can be harder to split than standard carbon steel. Results vary with nut hardness and condition. Check the manufacturer's guidance before attempting to split stainless fasteners.

Summary

This Blue Spot Tools nut splitter set removes seized fasteners between 12mm and 22mm. It works where conventional spanners and sockets cannot. The set carries the Blue Spot Tools Lifetime Guarantee.
